Automatic full field analysis of perfusion images gained by scanning laser Doppler flowmetry.
BACKGROUND Scanning laser Doppler flowmetry (SLDF) enables the measurement of the laser Doppler frequency shift in retinal tissue. This process allows the quantification of retinal and optic nerve head perfusion in an area of 2.7 mm x 0.7 mm within 2 seconds and with a spatial resolution of 10 microns x 10 microns. Owing to the local heterogeneity of the retinal microcirculation itself and to h...
متن کاملEvaluation of Carpal Tunnel Syndrome by Laser Doppler Flowmetry
Background:Autonomic disturbance can leads to blood flow changes that can be studied by various methods. Objective: To assess the blood flow changes in patients with severe carpal tunnel syndrome by laser Doppler flowmetry Methods:Ten patients with severe unilateral carpal tunnel syndrome confirmed by electrodiagnostic examination enrolled in this study. Patients comprised one man and nine wom...
متن کاملQuantitative Laser Doppler Flowmetry
vii-Abstract Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering in the 1970s, and a rapid evolvement followed during the 1980s with fiber based systems and improved signal analysis. The first i...
متن کاملEffects of dopexamine and positive end-expiratory pressure on intestinal blood flow and oxygenation: the perfusion pressure perspective.
OBJECTIVE To evaluate the net effects of the concomitant use of positive end-expiratory pressure (PEEP) and dopexamine on intestinal tissue perfusion and oxygenation during predefined artificial reductions in intestinal perfusion pressure (IPP). DESIGN Prospective, self-controlled, experimental study. SETTING University hospital research laboratory. SUBJECTS Seven female pigs. MEASUREME...
متن کاملContinuous monitoring of cortical perfusion by laser Doppler flowmetry in ventilated patients with head injury.
A method for monitoring cortical perfusion by laser Doppler flowmetry (LDF) in the neurointensive care unit is described. Out of 22 patients with head injuries, reliable and long term recordings were obtained in 16. Laser Doppler flowmetry registered changes in cortical microcirculatory flow in response to spontaneous waves of raised intracranial pressure, and to therapeutic manoeuvres that alt...
